Application filed February 19, 1919. Serial No. 277,982.

To all whom it may concern:

Be it known that GENKICHI YAMANOUCHI, subject of the Emperor of Japan,residing at No. 124 N akanocho, Yawata, Omorimachi, Ebara-gun, TokyoProvince, Japan,

has invented certain new and useful Im-- provements in Gramophones, ofwhich the following is a specification.

This invention has reference generally to improvements in musicalinstruments and more particularly relates to improved gramophones.

It is the primary aim and object of this invention to provide a deviceof the above character wherein the supporting box or case is of animproved construction and is designed to house the operating parts whenin active or inactive positions in addition to forming a cabinet forreceiving and retaining records.

An additional object of this invention is to provide a device of theabove mentioned character wherein improved means is employed formounting the tone arm and the sound reproducer within the box, thearrangement being such that the tone arm is received in a compartment inthe intermediate section of the box when the latter arm may be ar;

is folded or else the tone ranged in an operative position above therecord table when it is desired to operate the same.

More specific objects of this invention consists in the provision of afoldable amplifier or horn so designed that portions of the box form apart thereof; to provide an improved connection between the means forsupporting the tone arm and the horn; and finally to provide means forfastening the sections of the box in a closed position so be renderedportable when not in use.

Among the other aims and objects of this invention may be recited theprovisionof a device of the above mentioned character with a view tocompactness and wherein the number of parts are comparatively few, theconstruction simple, the cost of production low and the efliciency high.

Other objects as well as the nature, characteristic features and scopeof this invention will be more readily understood from the followingdescription taken in connection with the accompanying drawings andpointed out in the claims f r part of this specification. v 0 mmg a heinvention is clearly illustrated in the accompanying drawings in which Fg. 1 represents a longitudinal vertical sectional new of the device whenclosed the dotted hnes indicating the'trumpet 01 horn when extended andthe position assumed by the tone arm and sound reproducer when 1n anactive position.

F'1g. 2 1s a top plan view of the invention with the cover plateremoved, the amplifier or horn being shown in dotted lines to ind cateits position relative to the mouthpiece. i

F1g. 31s a fragmentary side elevational view showing the trumpet or hornextended, and

Fig. 4 is a perspective view of the inventlon showing the horn extended.

Similar characters of reference are employed in all of the abovedescribed views to lndicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there isprovided a box which includes a lower section 1 designed to accommodatea drawer 2 for receiving records 3. Carried with the lower section isthe intermediate sect-ion or compartment 4, the latter by a partiton 5near one side and the one corner to form a relatively narrow compartment6 and a large compartment 7 in which is ada ted to be nism not shown)for the machine. Projecting above the compartment 7 is a spindle 8 forthe revolving record table 9, the latter being positioned within andforming a bottom for the top section 10 of the box and this top sectionis preferabl pivotally connected by hinges 11. to t e intermediatesection so that it may be swung upwardly when desired but is normallyretained in a closed position by a catch 12.

tone arm 13 is provided, the outer end operably supporting a soundreproducer 14 which in turn receives a stylus or needle 15. With a viewtoward providing improved means for mounting the sound reproducer sothat it may be arranged in an active or inactive position in the box,the three sections are provided with a ment 16 in which is mounted astationary tube 17 while arranged within the tube is a being su'bdividedas,

arranged driving mechavertical compart-' Cir slider 18 forming a supportfor the downwardly bent inner end 19 of the tone arm. This slider isarranged in guides 20 and 1s capable of having vertical movement withlnthe tube but is normally supported by a coiled spring 21 also arrangedwithin the tube, the ends thereof bearing againstthe bottom of the lowersection and the slider and is tensioned so as to maintain the slider ina raised position. By this arrangement it will be seen that when in adepressed position the tone arm will be arranged within the smallhorizontal compartment 6 1n the intermediate section 4: and beneath therecord supporting table 9. When in th1s pos tion it is inactive and forconvenience additional records (not shown) may be arranged on thesupporting table. However when it is desired to start the machine thetable 9 may be removed to permit of the automatic extension of the tonearm and sound reproducer and subsequently the table and, one record maybe arranged in the proper position and the sound reproducer may coactwith such record for the playing thereof.

As intimated, an improved amplifier or horn is provided and in reducingthis feature of the invention to practice a cover plate 23 is providedand is hinged as at 24: to the top of the upper section. Membranes 25are now employed and are hinged to each other and to the cover plate 23and the top surface of the upper or top section 10 so as to form afoldable or collapsible horn. A mouth piece 26} is operably mountedinthe top of the top section while the flexible tube 27 forms animproved connection between this mouth piece and the stationary tube 17in the compartment. The tube 27 may be of such length as to accommodatethe necessary relative movement of the tone arm and amplifier, or, ifpreferred, it may be formed of rubber or equivalent elastic materialafiording: the necessary relative movement of these parts.

When the parts are in inactive position such as shown in Fig. 1 thecatch 12 is closed and the device may be readily transported by means ofa handle 28 which is connected to the intermediate section 4:.

It is believed in view of the foregoing description that a furtherdetailed description of the invention is entirely unnecessary.

Likewise it is believed that the advantages of the invention are readilyapparent.

It is also believed to be understood that various modifiations ofstructural details may be made so long as they fall within the spirit ofthe invention and the scope of the claims.

Having thus full described the invention what is claimed an desired tobe secured by Letters Patent is 1. The combination With a cabinetcomposed of a pluralit of sections, the upper of which is swinga lerelative to the intermediate section, a compartment in the intermediatesection, a record table rotatably and removably arranged above theintermediate section, a tone arm having a downwardly bent inner end, anda sound reproducer connected to the tone arm of a stationary tubearranged within the lowerand intermediate compartments for accommodatingthe downwardly bent end of the tone arm, a slider yieldingly mounted onthe tube and coacting with the tube to support the tone arm so that thetone arm and reproducer may be arranged in the compartment in theintermediate section or else upon the removal of the table moved to araised position so as to subsequently coact with the table.

2. An arrangement as claimed in claim 1 wherein a coiled spring isemployed and is arranged in the tube so as to be tensioned against theslider to automatically raise the tone arm and sound reproducer upon theremoval of the record table.

3. A device of the character described including in combination acabinet composed of lower, intermediate and upper sections, the uppersection being hinged with relation to the intermediate section, theintermediate section being provided with a tone arm receivingcompartment, the three sections being provided with a verticalcompartment, a tone arm having a downwardly bent inner end, a soundreproducer connected thereto, means within the vertical compartment forslidably and rotatably supporting the tone arm, resilient means coactingwith the last mentioned means and tensioned to force the tone arm andsound reproducer upwardly, a record table removably mounted above theintermediate compartment for retaining the tone arm and reproducer inthe small compartment in the intermediate section but removable topermit of the extension of the tone arm, a horn connected with the topof the top section, a mouth piece operably mounted in the top of the topsection and coacting with the horn and a flexible tube between the mouthpiece and the means for supporting the tone arm.

In testimony whereof he alllxes his signature in the presence of twowitnesses.
